I was doing some stuff outside at around 5 PM and I look up in the sky and right above me I see a huge 777 flying out of MSP, it didn't look like a Delta belly but couldn't make the airline. When I got home I checked Flight Aware, and I saw it was a Narita-ORD diversion.

I was also thinking if it was mechanical it seems that they decided to deviate to Mpls based on the flight aware map, somewhere over western Manitoba, didn't it make more sense to deviate to Fargo or Winnipeg? Instead of flying all the way to Mpls? and if they could make it to Mpls, why couldn't they make it to Chicago? I'm not complaining I'm just asking Or perhaps the 777 is too big for FAR or YWG?

Would you believe..... a failure with one of the in-flight entertainment system cooling fans? Caused a smell of smoke in the cabin which caused the diversion. Fan was disabled (so it wouldn't run = no more smoke) in MSP and replaced once the plane got to ORD.
